Licensing question about libobjc

[Andrew Pinski]

I notice that libobjc have a different exception than all of the other 
ones
which have an exception to the GPL.  Is there is a reason behind this?

The different between the libobjc exception and the one in 
libgcc/libstdc++ is that
the exception only takes into account when all sources were compiled 
with GCC.

Thanks,
Andrew Pinski
